Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a profound appearance by letting a surface layer have transparency so as to see the under layer under the surface layer, and coloring the under layer by pigment to make the density of pigment stronger than the surface layer. SOLUTION: A side cover shows a double layer construction of a surface layer 2 and an under layer 3. The surface layer 2 and the under layer 3 are formed out of synthetic resin of the same sort. The surface layer 2 is constituted of semitransparent film colored by pigment. Further, the under layer 3 is colored by pigment to be molded to be opaque, and both layers are piled up. A softened plate of double layer construction is placed on a mold 8, and air is sucked to draw vacuum by a vacuum device through a suction passage 9. Hereby, the softened plate is molded into a shape following to the inner wall 8a of the mold 8 by negative pressure. Because the molded side cover is semitransparent in the surface layer 2, the colored opaque under layer 3 on the under side can be seen, and hence a profound appearance is provided.

Abstract: PURPOSE:To correct a change in the modulation sensitivity due to the difference from an oscillated frequency by varying a reverse bias in response to the contorl voltage of a voltage controlled oscillator in a frequency synthesizer varying the reverse bias to generate an FM modulation wave. CONSTITUTION:A control voltage 20 is fed to a gate of an N-channel FET 60 and a DC bias is superimposed on a modulation signal and the result is fed to a varactor diode of a voltage controlled oscillator 2. When the oscillated frequency of the voltage controlled oscillator 2 is high, a control voltage 20 fed to a gate terminal of the FET 60 gets higher. When the resistance of resistors 50, 51 is selected in a way that the drain current of the FET 60 is saturated, the DC bias of the FET 60 is decreased by a product R ps being the product between the increment  Ips of the drain current and the resistance R of a resistor 50. Then the capacitance of the varactor diode is increased, the modulation sensitivity is lowered to correct the relation between the oscillated frequency and the modulation sensitivity to be flat.

Title: Pressure reducing valve
Inventor: KOYAMA MITSUHIRO
IPC: G05D16/06
Filed: 1988-08-11
Abstract: PURPOSE:To prevent a chattering phenomenon from being generated by arranging a check valve, for which a small hole is opened on a valve body, in a secondary pressure detecting path which induces secondary side pressure to a diaphragm lower surface. CONSTITUTION:The elastic force of a pressure setting spring is applied to the upper surface of the diaphragm and the secondary side pressure is applied to the lower surface. Then, a valve port is opened and closed by the valve body according to the balance between both power and flow rate is controlled. Then, the secondary side pressure is kept to setting pressure. A check valve 74, for which a small hole 86 is opened on a valve body 84, is arranged in a secondary pressure detecting path which induces the secondary side pressure to the diaphragm lower surface. Accordingly, when a main valve is rapidly closed and the secondary side pressure is rapidly lowered, the fluid pressure of the diaphragm lower surface is not discharged to a secondary side soon but gradually exhausted from the small hole 86 of the valve body by the operation of the check valve 74. When the secondary pressure rises up rapidly, the pressure is not transmitted to the diaphragm soon but gradually passed through the small hole of the valve body and transmitted by the operation of the check valve. Thus, the chattering is canceled.
